The reserve was created in 1995 to combat the loss of reedbeds, which had declined by 90% in the UK at that time.
It is the only site in the UK where common cranes can be regularly observed breeding in a managed reedbed habitat.
The project converted 280 hectares of carrot and sugar beet fields into wetlands.
Otters have established holts within the reserve, making it one of the most reliable places to spot them in East Anglia.
The water levels are strictly controlled using a series of sluices to mimic natural winter flooding patterns.
Golden orioles occasionally nested here in the early 2000s, though they are now rare visitors to the site.
RSPB Lakenheath Fen is a landscape-scale wetland restoration project that successfully converted former arable farmland into a thriving reedbed habitat. It is notable for being the primary site in the United Kingdom where Eurasian bitterns and common cranes have returned to breed after long absences. The reserve spans approximately 300 hectares, featuring diverse habitats including open water, fen, grassland, and woodland. It serves as a vital corridor for migratory species and supports a significant population of otters and water voles. Visitors can navigate an extensive trail network that links various hides and viewing platforms situated throughout the marshlands. The site is actively managed to maintain specific water levels necessary to support reed-dependent birds and rare flora. It functions as a critical example of how intensive industrial agriculture can be transformed into a productive ecological haven.
The Mere Hide provides excellent eye-level views of the open water and frequent waterfowl activity.
Bring high-quality binoculars as the wildlife, particularly bitterns, often remains at a significant distance from the hides.
Check the 'What's being seen' board at the visitor center upon arrival for the latest bird sightings reported by other visitors.
Walk the full length of the reserve to the washland viewpoint for the best chances of spotting large raptors like marsh harriers.
Ignoring the trail markers; wandering off-path can damage sensitive reedbed habitats and disturb protected species.
Keep dogs on a short lead at all times to avoid disturbing nesting ground birds; remain silent in bird hides.
